Lighting window allows non-cube map texture for Environment Reflections, throwing invalid texture type (2D) error

-

Nov 14, 2025

Steps to reproduce:
1. Create new Unity project
2. Open Lighting window (Window > Rendering > Lighting)
3. Press on Environment tab
4. Change Environment Reflections > Source to Custom
5. In Cubemap change None (Texture) to “Default-Particle”
6. Observe the Console window

Actual results: Error is thrown in the Console window: “RenderSettings customReflection texture has invalid type, 2D given while only CUBE is supported. Custom reflection texture will not be used
UnityEngine.UIElements.EventDispatchUtilities:HandleEvent_BubbleUpHandleEvent (UnityEngine.UIElements.EventBase,UnityEngine.UIElements.BaseVisualElementPanel,UnityEngine.UIElements.VisualElement,bool) (at /Users/bokken/build/output/unity/unity/Mod”

Expected results: Invalid type texture should not be allowed to be selected, no errors are thrown in the Console window

Reproducible with versions: 6000.0.62f1, 6000.2.13f1, 6000.3.0f1, 6000.4.0a5, 6000.5.0a1

Tested on (OS): Ubuntu 24.04, macOS Tahoe 26.0 (M1)
